Silver foil

This is another snowflake from wonderful snowfall of January 16, 2014. This medium size crystal, as well as many others from that day, have interesting frozen bubbles of rime on it's surface. Overall amount of these bubbles is low, but almost every bubble have something like "impact crater" around it (like ring waves in the pond from thrown stone).

This snowflake was captured on large sheet of glass with LED back lighting, using Canon Powershot A650is with additional lens Helios 44, reversely mounted in front of camera optics, for better magnification. 8 identical RAW photos, captured as quick series, was averaged for better SNR (signal-to-noise ratio) of this image.
